Technical Field

[0001] This utility model relates to the field of refrigeration cabinet technology, specifically a multi-purpose liquid-cooled cabinet. Background Technology

[0002] With the rapid development of the modern economy, more and more multi-purpose server racks are being installed on-site. Some multi-purpose server racks operate in harsh environments, requiring continuous operation in high-temperature and dusty conditions for extended periods. Therefore, heat dissipation devices are needed to address heat dissipation issues.

[0003] A search revealed a device for cooling a server rack, patent publication number CN220858788U. The device includes a server rack body with ventilation holes on its side, each containing an external dust filter. A cooling assembly is mounted on the server rack body and includes a fan, a locking block, an inner cover, and an inner dust filter. The server rack body has mounting holes on its side, with the fan engaging with the mounting holes. The locking block is fixedly connected to the fan. Two locking grooves are also present on the side of the server rack body. During the implementation of this solution, the following problem was found in the existing technology: relying solely on a fan for cooling is insufficient to guarantee the cooling effect of the rack. Therefore, there is an urgent need to design a multi-purpose liquid-cooled server rack to solve this problem. Utility Model Content

[0004] The purpose of this utility model is to provide a multi-purpose liquid-cooled cabinet to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A multi-purpose liquid-cooled cabinet includes a cabinet body, a cover plate rotatably connected to one outer wall of the cabinet body, an equipment rack provided on the inner wall of the cabinet body, the equipment rack being hollow, multiple airflow channels opened on the bottom outer wall of the equipment rack, a liquid collection tank fixedly connected to the bottom of the cabinet body, a circulating liquid cooling mechanism provided between the liquid collection tank and the equipment rack, a rotating air intake mechanism provided at the bottom of the inner wall of the cabinet body, an airflow circulation mechanism provided at the top of the cabinet body, and an auxiliary cooling mechanism provided inside the liquid collection tank.

[0007] Preferably, the circulating liquid cooling mechanism includes a first liquid guiding hose and a second liquid guiding hose, a liquid pump and a liquid collection tank are fixedly connected, the other end of the second liquid guiding hose is fixedly connected to the equipment frame, and both ends of the first liquid guiding hose are fixedly connected to the equipment frame and the liquid collection tank respectively, and the equipment frame has thermal conductivity.

[0008] Preferably, the rotating air intake mechanism includes an air guide plate and a rotating shaft. A base box is fixedly connected to the bottom of the liquid collection tank, a motor is fixedly connected to the bottom of the base box, the top of the motor is fixedly connected to the rotating shaft, the rotating shaft is hollow, an air guide hole is opened on the outer wall of the rotating shaft, the air guide hole is located inside the base box, an air inlet pipe is fixedly connected to the outer wall of the base box, an air pump is fixedly connected to the outer wall of the air inlet pipe, the top of the rotating shaft is fixedly connected to the air guide plate, and multiple air outlet pipes are fixedly connected to the top of the air guide plate.

[0009] Preferably, the auxiliary cooling mechanism includes a cooling plate and a heat dissipation device, wherein the cooling plate is fixedly connected to the inner wall of the liquid collection tank, and the heat dissipation device is fixedly connected to the cooling plate.

[0010] Preferably, the inner wall of the liquid collection tank is provided with multiple gas distribution pipes, and the gas distribution pipes are fixedly connected to the rotating shaft.

[0011] Preferably, the airflow mechanism includes a protective plate and an exhaust channel. The exhaust channel is fixedly connected to the outer wall of the top of the cabinet. The outer wall of the exhaust channel has multiple air holes. The protective plate is located at the top of the exhaust channel. Multiple support rods are fixedly connected between the protective plate and the cabinet.

[0012] Preferably, multiple springs and dampers are fixedly connected to the outer walls at both ends of the equipment rack, and the other end of the springs and dampers is fixedly connected to the inner wall of the cabinet.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] In this invention, the circulating liquid cooling mechanism uses a pump to drive the coolant in the collection tank, which is then transported to the equipment rack via a second liquid guide hose. The rack's thermal conductivity absorbs heat from the equipment inside the cabinet, and the coolant then flows back to the collection tank via a first liquid guide hose, achieving closed-loop cooling. Simultaneously, the air pump of the rotating air intake mechanism injects air into the bottom box through the air intake pipe, which then enters the air distribution pipe through the air guide hole of the rotating shaft and is ejected upwards through the air outlet pipe of the air guide plate, forming an upward airflow. This airflow carries away heat from the equipment surface through the airflow channel at the bottom of the equipment rack, forming a "three-dimensional" heat dissipation network with the liquid cooling system. The cooling fins of the auxiliary cooling mechanism further cool the coolant in the collection tank, while the heat dissipation equipment dissipates the heat generated by the cooling fins, ensuring liquid cooling efficiency. This design can control the temperature inside the cabinet within a safe range in high-temperature environments, preventing equipment shutdown due to overheating.

[0015] In this invention, the motor-driven rotating shaft of the rotating air intake mechanism rotates, causing the air guide plate and air outlet pipe to periodically change the airflow direction, avoiding the heat dissipation blind spots caused by the traditional fixed airflow direction. This ensures that all equipment in the cabinet can be effectively cooled. The exhaust channel of the airflow mechanism quickly discharges hot air through the top air hole. The protective plate prevents dust and debris from entering, ensuring smooth airflow. The equipment rack is connected to the cabinet through springs and dampers, which can absorb the vibration of the equipment during operation and reduce the loosening of parts caused by resonance. At the same time, it provides a buffer for the liquid cooling pipeline and avoids leakage caused by hard impact. This design not only improves the uniformity of heat dissipation, but also extends the service life of the cabinet and internal equipment through multiple shock absorption structures. It is suitable for industrial environments with high dust and high vibration. Attached Figure Description

[0029] The working principle of this utility model is as follows: When the cabinet is working, the liquid pump 18 starts, pressing the coolant in the collection tank 7 into the equipment rack 2 through the second liquid guiding hose 21. After absorbing the heat of the equipment, it flows back through the first liquid guiding hose 15. The cooling plate 19 cools the returning coolant, and the heat dissipation device 10 dissipates the heat. At the same time, the air pump 24 supplies air to the bottom box 8 through the air inlet pipe 23. The air enters the air distribution pipe 17 through the air guide hole 22 of the rotating shaft 16, and is sprayed upward through the air outlet pipe 20 of the air guide plate 14. It passes through the airflow channel 6 at the bottom of the equipment rack 2 and carries away the heat from the surface of the equipment. The hot air is discharged through the air hole 12 of the exhaust channel 13 at the top of the cabinet. The motor 9 drives the rotating shaft 16 to rotate, causing the airflow direction to change periodically, ensuring uniform heat dissipation. The equipment rack 2 is damped by the spring 4 and the damper 3 to ensure the stable operation of the liquid cooling system. The whole mechanism realizes the dual functions of liquid cooling and air cooling combined heat dissipation and equipment protection.
